摘　　要：辽宁省水科院在小龙口水库坝基砂卵石层防渗施工中,将高压喷射灌浆与静压充填灌浆结合在一起,构筑夹心结构防渗墙。与高喷板墙相比,该种形式防渗墙厚度增加了3~4倍,单位体积墙体水泥含量增加了15%,从而使墙体的耐久性得到很大程度的提高。文章就这种新型夹心防渗墙在小龙口水库坝基防渗中的设计、施工及防渗效果作了介绍。The sandwich structure cut-off wall is built by the combination of the high pressure jet grouting and static pressure filling grouting in the construction of seepage prevention for the sand and gravel layer of Xiaolongkou reservoir dam foundation.Compared with high pressure jet grouting cut-off wall,this wall thickness increases 3~4 times,the cement content per unit volume increases 15%,the durability improves largely.The paper introduces the application of new sandwich structure cut-off wall in the design,construction and effect of seepage prevention of Xiaolongkou reservoir dam foundation.
